Step-by-step explanation
The composite figure comprises of a cone balanced on top of cylinder
Step-by-step explanation:
The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r
Then the volume of the cone will be 
Then the volume of the cylinder will be 

The total volume of the composite figure will be V, where


let the height of cone and cylinder be same
The volume of the composite figure will be 

Hence 
Thecomposite figure comprises of a cone balanced on top of cylinder
Where are the numbers at? And if you need a formula for that, A=2(wl+hl+hw)
Do you want the exact form or decimal form?
